Title: Flash device for flash photography
Inventor: TAMURA KOJI
IPC: G03B15/05
Filed: 1995-10-05
Abstract: PROBLEM TO BE SOLVED: To compactly arrange a photometric sensor for monitor on the periphery of a light emitting part and to save parts so as to reduce a cost by taking the irregularly reflected light in glass for absorbing light rays into this photometric sensor. SOLUTION: The photometric sensor 7 is disposed within a refractive index shade cover 12 on the outer side of a reflection shade 3 approximately parallel with the optical axis of emitted light and perpendicularly to the surface of the glass 11 for absorbing heat rays so as to face the same direction as the illumination direction. The flash light emitted from a flash light emitting tube 4 is cast forward through the glass 11 for absorbing the heat rays at the time of metering the light with a light emitting monitor in this constitution. The flash light reflects irregularly between the plate layers of the glass at the time when the flash light passes the glass 11 for absorbing the heat rays.  In such a case, the greater part of the reflected light is released toward the end surface direction of the glass 11 for absorbing the heat rays but part of the scattered light is made incident on the photometric sensor 7. This scattered light is picked up by the photometric sensor 7, by which the photometry is executed. As a result, the constitution is simplified, by which the cost reduction by the decreased number of parts and the saving of the spacing are made possible.

Abstract: PURPOSE:To obtain the radiation sensitive compsn. which has high transmittance to short wavelength UV rays and has excellent stability by incorporating carboxylic acid or carboxylic acid deriv., a compd. having a hydroxyl group and an acid precursor which generates an acid by irradiation with active chemical rays. CONSTITUTION:The carboxylic acid or the carboxylic acid deriv. or both thereof, the compd. having the hydroxyl group and the acid precursor which generates the acid by irradiation with the active chemical rays are incorporated into this compsn. The acid precursor of the part irradiated with radiations generates the strong acid and, with this acid as a catalyst, the hydroxyl group and the carboxylic acid are esterified, by which this compsn. is made insoluble in an alkaline developing soln. The compsn. thus acts as a negative type photosensitive compsn.

Just a slight irradiation quantity of the radiations for the purpose of latent image formation is necessitated. The radiation sensitive compsn. having the high transmittance to the short wavelength UV rays and the excellent stability is obtd. in this way.
